Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

open access: yesAdvanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Spectral Tuning of Hyperbolic Shear Polaritons in Monoclinic Gallium Oxide via Isotopic Substitution

open access: yesAdvanced Materials, EarlyView.
Spectral tuning of highly directional hyperbolic shear polaritons is realized via isotopic substitution of 16O to 18O in monoclinic β$\beta$‐phase gallium oxide. A red‐shift of almost 40 cm−1 is experimentally demonstrated with near‐field imaging, corroborated by the permittivity change extracted from far‐field experiments and density functional theory.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

open access: yesAdvanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

open access: yesAdvanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.
